Title: Compass capable of recognizing visually radius of circle to be drawn
Inventor: SUZUKI YASUFUMI
IPC: G01B3/16
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain a compass capable of recognizing a radius of a circle to be drawn in order to appreciate a definition of the circle by a method wherein a radius displaying material of a length corresponding to the radius of the circle to be drawn is linearly extended over between both lower end parts of a pair of compass legs, and upper end parts of the legs are, in a freely openable manner, connected to each other. SOLUTION: For a compass C1 , upper end parts of a pair of compass legs 1, 2 are intersected mutually in a structure in which a thickness is not increased, the intersected part is stored between respective hanging down pieces 3a of a connecting bracket 3 of which a side form is U-shaped, and they are integrally connected via a connecting pin 4. When an open angle of a pair of the compass legs 1, 2 is increased, a radius displaying wire W is drawn out from a wire through hole at the lower end part of the compass leg 1 against restoring force of a coil spring 11, and extended over between the lower end parts of a pair of compass legs 1, 2. When a circle is drawn under this state, its radius itself can be visually recognized even in the midst of drawing the circle, which becomes helpful in appreciating a definition of the circle.

IPC: E04B1/68
Filed: 1988-06-21
Abstract: PURPOSE:To obtain a composite sealing material capable of maintaining the better watertightness over an extended period of time by applying a water swelling elastomer to a groove in a contact section of a seal body of a non- water swelling elastomer. CONSTITUTION:A water swelling elastomer 14 is applied to a groove 12 in a contact section which is a seal part of a seal body 11 of a non-water swelling elastomer. Most part of such a composite sealing material 10 is constituted of the non-water swelling elastomer, so that contact surface compressive reaction force necessary for watertightness is obtained, and, at the same time, a water leakage in the early submersion is prevented. An amount of compressive deformation of the sealing material 10 is reduced by the water swelling elastomer 14 of the groove 12, so that it is prevented to act strong compressive reaction force on a structure to eliminate unloadings. Accordingly, the better watertightness can be maintained over an extended period of time.
